# AsyncTimeout - `setTimeout()` and `setInterval()` for async code.
The class `AsyncTimeout(function, timeout)`.
An async wrapper around `setTimeout()`, and an async iterator wrapper around `setInterval()`, which resolves to/yields the return value of the supplied function for both `.timeout()` and `.interval()` respectively.
## Methods
There are two methods on the class `AsyncTimeout(func, time)`:
*`timeout()`: Creates an `await`able promise that will resolve to the value of `func()` when the timeout `time` is reached.
*`interval()`: Creates a `for await`able async iterator that will resolve to the value of `func()` each `time` it is called. To cancel the interval, simply break from the loop or stop calling `.next()` on the returned async iterator.
## Parameters
*`thing` - The function to call after the timeout/interval. The result of the promise (or the yield for `interval()`) is the result of this function call. If the funtion throws, then the rejection of the promise will be that error thrown.
*`interval` - The time to wait for the timeout or interval
## Example usages
See `example()` in the file for detail.
### `setTimeout()` promisified
`await (new AsyncTimeout(() => "value", 100)).timeout() /* === "value" */` is `setTimeout(()=> "value", 100)` promisified.
### `setInterval()` async iterator-ifyed.
`for await (const value of new AsyncTimeout(() => "value", 100)).interval()) { /* value === "value" */ }` is `setInterval(()=> "value", 100)` with each interval promisified.
`value` will be the result of each interval call, so the function passed can capture, interact with, and return whatever it wants during the interval and each `value` will be the result of it being called again at each interval (as is expected.)
This is an infinite iterator. To cancel the interval, simply break out of the `for await` loop or otherwise stop using the iterator returned from `.interval()`.
